摘　　要：对拟板法建立的偏微分方程,用最小二采配点法求解,进而求出空间网架结构在各类边界支承下的杆件内力。此法扩大了拟板法的应用范围。算例结果表明,本文算法与其它近似方法相比,计算精度较高。The partial differential equation given by simulated plate methodis solved by the least-square collocation method,and the internal forcesof members are obtained for space truss with boundary conditions.Thismethod extends the applicable region for simulated plate method,and hassome appealing features such as concept simplicity,easiness of a com-puter programme edited and its small calculating work,Finally,anumerical example is presented in this paper.
